I will create knowledge graphs and ontologies

I will design and build knowledge graphs using ontologies

I specialize in designing, modeling, and implementing knowledge graphs backed by well-defined ontologies. Whether youre working with complex data, need better semantic structure, or want to enable reasoning and advanced querying, I can help you turn raw data into a meaningful, interconnected knowledge system.

What I offer

• Ontology design & modeling
• Domain analysis and concept extraction
• Class hierarchies, properties, constraints
• OWL / RDF / RDFSbased ontologies
• Knowledge graph creation
• Transforming structured or unstructured data into RDF graphs
• Entity modeling and relationship mapping
• Data integration from multiple sources
• Semantic enrichment & reasoning
• Linking entities using shared vocabularies
• Rule-based and ontology-driven inference
• Querying & validation
• SPARQL queries for analytics and insights
• Data validation using SHACL
• Documentation & guidance
• Clear documentation of the ontology and graph model
• Explanations tailored to both technical and business stakeholders

Use cases

• Knowledge management systems
• Academic or research knowledge graphs
• Semantic search and recommendation
• AI / ML feature enrichment
